Good
- Carefully re-do this troubleshooting guide steps.
- If problem still occurs, replace AVNT and then go to "VERIFICATION OF REPAIR " procedure.
No Good
- Repair open or short in circuit and then go to "VERIFICATION OF REPAIR " procedure.
- If no problems were found with the circuits or connectors, replace the handsfree MIC and go to "VERIFICATION OF REPAIR " procedure.
